Zigbee end point device discovery

Hello,

I have some Zigbee devices which I would like to use.
Old gateway was cloud based and the service was shut down.
As I understand I should be able to create new gateway/coordinator based on Xbee Zigbee modules.
I have XBee S2 device with USB adapter. I have uploaded the following firmware: XB24-ZB, Coordinator API, 21A7. All settings are default.
I’m unable to find any remote devices during scan (yes I have reset the end devices so they would try to connect).
In long run I would like to integrate all devices with OpenHab2 over Raspberry Pi3, but first of all I should get the devices talking to one-another through XCTU.
Any ideas what could be wrong?

From your question I’m guessing your “ZigBee devices” are third party and not Digi XBee-based devices?

They are likely on a network/security configuration which is not compatible with XBee defaults.

If your devices are ZigBee Home Automation you could follow instructions at http://knowledge.digi.com/articles/Knowledge_Base_Article/Zigbee-Home-Automation.
